SELF-DUMPING MINE CAGE.

Specification of Letters Patent. Patented M 21 1922 Application filedOctober 9, 1920. Serial 1T0. 415,757.

7 To all whom it may concern:

loaded cars being raised by said hoisting cage when apredetermined levelhas been reached, the operations of dumping and restoring, the car tooriginal position being effected automatically, all as will behereinafter more fully described and claimed.

Another object is to adapt the cage for carrying men, mules, supplies,etc, where dumping is undesirable or unnecessary Referring to theaccompanying drawings which are made a part hereof and on which similarreference characters indicate similar parts,

Figure 1 is a view showlng a mine ho sting cage constructed inaccordance wlth my said invention with a loaded car thereon,

normal position being shown in whole lines and the position which theparts occupy when dumped, in dotted lines,

Figure 2, a view looking atthe same parts toward the front end of thecar, and

'Figure 3, a section on line 33 of Figure 2,

In said drawings the portions marked A represent the track; or timberson which the mine cage runs, B the frame of the mine cage, and C thecar. 7 These several parts are in themselves of a construction andarrangement substantially like what is in ordinary use or may 7 be ofany appropriate construction and arrangement. The hoisting cage B isconnected at 10 to any hoisting means operated by any appropriatehoisting power. The cage B carries a main platform comprising fixed sidemembers 10 and a swinging trap or platform 11 hinged to the fixedmembers at 12 and carrying rails 13 for the car C adapted to connectwith the track system of a mine so that the car may be run on andoff-the cage as desired. The car it,- self is preferably of the typeshown in my Patent No. 1,327,255,1lan. 6, 1920, known as the Reynoldsautomatic mine car and needs no specific description here. It has amovable bottom'portion hinged at one end and adapted to follow themovableplatform 11 down and up.

The side sills of platform 11 have downwardly projecting portions 14which are provided with lower inclined faces 15 and 16 sloping down fromthe front ends of the sills and separated by points 17, and the face 16terminating in a stop 18. Diagonal supporting rods 19 pivoted at 20, areprovided with rollers 21 at their lower ends supported by a shaft 22held in blocks 23 at the lower ends of bars 19. Rollers 21 extend, undersill extensions 14, and are normally held in position in front of points17 as shown in Figure 1 by the cam action of faces 15. Rods 19 passbetween rollers 2 1, 24; on longitudinal extending bars. 25, guidedbetween fixed bars 26, 26.

At one end of each bar 25 is a roller 27 adapted to bear on a cam 28 andat the other end the bar is reduced to a point 29 adapted to bear on apositioning roller 30.

When the movable platform is lowered to dump the car it is supported atits forward end by a cross bar 31 between two yokes 32 forming a portionof cage B.

On the fixed platform members 10 are provided supports 33 for the bodyof the car to hold the same up when the bottom is lowered for dumping.Latches 34: are pivoted on the supports to engage the car at each endand hold it in place on the rails 13. When the car is to be run off thecage the latches at one end of the car will be lifted out of the way.

My improved mine cage is also adapted dumping device for special usessuch as those indicated. 7

In operation, when my car is lowered, cams 28 will move bars 25 to theright (Fig. 1) whereupon rollers 24 swing bars I 19 to ride away fromstop 18 along camface 16 gradually lifting the trap and attached partsand when the rollers pass point 17 and ride against faces 15 the trap ispractically locked in place. On the return trip, the parts remain asdescribed untilpoint 29 strikes roller 30* when the: trap: is:

uickly lowered by a reverse operation of t e parts enumerated, whichassumethe dotted line position (Fig. 1). The coal or other materialwslidesgently but quickly out of and away from the car, which is thenready to repeat the operation.

My invention. is not limited to the em:

bodiment shown since variousmodifications,

will readily occur to those skilled in the art. The true scope; thereofis indicated by the appended'claims. M
